IMPROVEMENT IN CORN-DROPFERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, MAJOR ROBERT WILsox CALD- WELL, of Jackson, in thecounty of J ackson and State of Ohio, have invented a-rrew and improved Corn-Dropper; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and rise the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvement in apparatus for dropping corn, and consists in the combination of an opcillating valve, valve-case, and springs, the same being arranged to operate in connection with a suitable cylinder or case, as hereinafter described.

Figure 1 is a sectional elevation of my improved" corn-dropper, and

Figure 2 is a sectional elevation of the valve, showing a slight variation in the construction.

Similar lettersof reference indicate corresponding parts.

A is the sheet-metal cylinder, having a removable cover, B, for supplying the corn to the chamber above the partition E, and the upper hub of the case 1* of the valve G. The said caseis made in cylindrical or other form, with a pocket, H, opposite the partition E, and let into the side of the case A with its transverse axis. parallel to the longitudinal axis of the case. i

The upper wall of the pocket H is a short radial plate, I, extending from the periphery of the case in-' 'ward, and fitting against the periphery of the valve G,-

which is cylindricalfor the most part, with an extension, K, at the lower side working agaiust-the inner face of the valve-case F,'helow ,the pocket H. This valve is pivoted in the axis of the valve-cas'e, and is provided with a wire spring, L, at the back, which presses it against theplate I and the lower part of the case F. It is moved back and forth to ope ran'd close the escape-passage, by working the rodM up and down at the proper time.

Thepartition E is provided with a cut-off brush, N,

against which the projection K closes the'passagewhen turned upward.

Figure 2 represents a slight modification of the form .of the valve, and a different arrangement of the spring 6 for holding the valve to its seat; the said spring being placed on a rod, 0', extending from. the axis of the valve ont' thro'uglf the case, between the inner wall of the case and"th'e"valve; 1n this'case'," the working-rod M is to be attached to the rod 0'.
